IMPROVEMENT IN FEED-WHEELS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 48,206, dated June 13,1865.

To all 'whom it may concern.-

Be it known that I, Louis PLANER, ot the city, county, and State of NewYork, have invented a new and useful Improvement in Feed- Wheels forSewing-Machines; and I do hereby declare the following to be a full,clear, and exact description thereof, reference being had to theaccompanying drawings, figures, and letters thereon, making part of thisspecification.

Ot' the said drawings, Figure l shows a back view, a portion of thetable being removed to show the working parts. Fig. 2 is an end view.Fig. 3 is a full-size top view of the feed-dog removed from the wheel.Figs. 4 and 5 show parts of theieedlever in detail.

Similar letters of reference indicate like parts in all the drawings.

. machine a mechanism for causing the wheel to progress regularly, andfor readily adjusting the stitches, as will be fully set forth.

To enable others skilled in the art to make and use my invention, I willdescribe the construction and operation thereof. A represents the bed ofa sewingmachine, to which is secured a goose-neck, B, for supporting theoperative parts above the table. In this goose-neck, in proper journals,V V, is a shaft, C, to which is secured a serrated pulley, I, fordriving the machine, and a diskwheel, J, and also a shaft, D, which hasjournals at W W, one end being provided with a disk-wheel, L, which isconnected to the wheel J by means ot' a pin, P, to which is connectedthe rod H for driving the rock-shaft below the table, while the otherend of the shaft D is provided with a crank-wheel, K.

To the front of the goose-neck is secured the face-plate E by screws.The needle-bar and presser-rod slide in proper grooves in this plate E.

To the needle-bar is attached a heart-shaped groove-plate, C', in whichis inserted a roller, b', on the crank in the wheel K.

To the upper partof the goose-neck is se-4 cured a small bracket, F,which supports the apparatus for controlling the needle-threud To thetable are cast lugs U U, which support the shaft G. OnA this shaft, atone end, is an arm, X', which is connected to the rod H at Z', while theother end has an arm, d', which, by means of a rod, e', pivoted by apin, f',

drives the shuttle-carrier Z. On this shaft G, outside of the arm d', isa cam, T, which operates the feed-lever c by means of a short arm, b,which is tted to slide on the lever c, as shown in Figs. 2, 4, and 5.

The feed-wheel A' is bored for the stud F', and has a small finished hubupon which the lever is inserted. The Wheel has a concentric f ring orlange, G', made perfectly true with the Vaxis of the wheel, and has itsperiphery roughened to grasp and advance the material to be sewed. Thewheel is supported by the stud F and nut M in the hanger B', as plainlyshown in Figs. 1 and 2. Inside of the hanger I insert a friction-block,f, which has a spring, and which is made to press against the side ofthe wheel by means of a screw, g, passed through B', which screw ispointed and lits a small hole in the spring-block f and keeps it inplace. The feed-dog c' has a groove, L', Fig. 5, cut to lit the ring G'on the wheel, and is cut away at k' to receive an ear, f", on thefeed-lever, which keeps the dog in place.

The feed-lever a, has its fulcrum on the hub of the feed-wheel, and isdrilled and tapped with a screw-thread, as shown in Fig. 4. To the endof the lever, which is square, I t a small arm, b, having a squaresocket, so that it will slide freely ou the lever. In this socket Iinsert a screw, e, having a shoulder', so that it shall have a bearingand turn freely within the arm b, and outside of the arm I insert aclamp-nut, o,the screw c having a thread therefor, and outside of thisclamp-nut c I put a thumb and linger nut, d, which is made fast on thescrew e, and as this nut d is turned up or back on the lever the arm bis moved, and the stitch is regulated by a greater or less Vibration ofthe feed-lever a, operated by the cam T. As the lever a is vibrated theshort end bites upon the feed-dog at the point S' and gives a powerfulleverage and forces the wheel forward in the direction of the arrow, andthe lever drops by its gravity and the aid of the spring i as soon asreleased by the cam. The dog c' is reacted by the spring t', which restsagainst a pin, It, while the dog rests against the lever a, which actsas a fulcrum.

Operation: The machine is threaded up in the ordinary way for the needleand shuttle, and the material tobe sewed is placed upon the feed-wheeland the presser-foot h' on the bar O let down" by the lever N and heldby the coil-spring v', and motion being given to the machine, the needlewill have a reciprocating motion by means of the crank-wheel K andgroove-cam C', secured to the needle-bar a. As the shaft revolves therod H will give a rocking motion by means ofthe arm X to the shaft G,which drives the shuttle by the arm d and the feed-lever by the cam T,Which is eutout on the opposite side, the same as seen in Fig. 2. Ateach revolution of the shaft@ the needle Will penetrate the material andreact to form a loop of thread, through which loop the shuttle Will passduring the pause of the needle, and as the needle ascends the materialis fed along during the time the needle is out of the material by thecam T raising the feed-le-
